there have been a few simlar threads posted but its time for me to make a final decision what i am going to go with on the 1600tp buggy...

i am a fan of twin cannons. for access and visual appeal reasons... is there any conclusive evidence and experience that these cause the rumoured problems? your experiences with them?

i also like marine boys setup with motorbike pipes...

I have cannons on mine, they are ok but a 4 into 1 system is the go if you want to get the most out of your engine. I think a 4 into 1 sounds better too.

cannons WILL send you crazy from how loud they are
best to get the 4 into 1 with a quiet pack

Thinking of using cannons on the Manx we are re-buliding.

Toying with the idea of using motorbike mufflers.

The 4 into 1 systems I have seen all hang out the back to far for my liking. Have to extend the barwork as well to cover the hot bits.

Buy one of each type of system you can possibly find and keep swapping them till you get the one you like....:cussing

4 into 1's

why cause I hate telling people I told you so.........

Cannons are cheap but rob you of power and drive comfort. Bike muffler are just that, made for bikes and should stay there.

guys, the more noise ya motor makes the less comfy the car will be. don't put cannons on it, they are just plain offensive and your neighbours will hate you too.
You want something nice and quiet that helps the motor produce as much torque as pos. Don't worry about power, the weight loss of a buggy makes a 1600 feel quick anyway.

have u tried fitting those cannons up yet air fooled?

nah man...

in accordance with my buggy routine they have to sit in the corner for a good month or so before i do more then drink beer and look at them haha, actually to be honest i chucked em in the back of my work truck and there they stayed! the storeman at work has now put them down the back of the shed so i guess i better go get em haha.... thanks for reminding me.. hahaha

loud n offencive?? with the right coice of muffler you can get all the back pressure you need n still stay quiet (if you really want).imo it is the lack of exhaust speed that robs you of pwr
personally i love the sound of cannons negates the need of a heavy, highly thiefable, and expensive stereo system go horizontal 4 sounds mmmmVWmmmmm:bounce
just my 2cnn[ Edited on 7-8-2005 by dubbill ]

I stuck with my twin cannons simply due to the fact that 4 into 1 looks ugly. It sticks out and really theres no good looking way to have any four into one system from what i have seen. + i like the noise. and i accept the fact that i am not getting all the power out of my engine that i could but i prefer to loose that .5sec or so down the quarter and keep my baby looking good

The buggy has some extra space behind the engine, so hopefully looking at merging the pipes behind the engine (somehow??) and still have the dual exhaust.

hey rupsta, check out marc and kathys recently made baja.... same thing along what your talking about.... not the best photos of the pipework but you get the idea...

jonnyb once told me u could use a commodore merge from the 2 pipes and they match up perfectly with the twin cannons if u want to put a quieter muffler past that.

Hi peoples.
The exhust on my BAJA uses the front part of the cannons from heads to where they join then they made a system so they joined up for a 4 into 1 and still use the same short engine cage that the cannons use.
Look at the picture below it could be done neater but it works ..

I've had to look at the exhaust question recently....and I'm staying with a standard beetle exhaust. I had a lot of hassles in town finding anyone that would make an exhaust for a buggy....and the couple that would have said that not only with the cost be high, but it will take them a lot of time to do and the system will be noisy.

And.....when the first rego check ádvised' me that my exhaust noise was 'borderline' with a standard beetle exhaust, I can't afford to go any louder. I can't justify paying big bucks and losing the car for a long period, just to have a louder car that won't pass rego!

I checked with some out-of-town places (interstate) and although some of the prices were better, they all admitted their system will be louder than standard. So.....bug exhaust for me!

Just a foot note the above system is very quiet, the engine is louder that the exhust

Marc

I like the idea of a four into one system behind my engine, has anyone ever attempted this?

I just dont want any ugly pipework covering my beautiful crome engine (main reason for not going four into one and keeping the cannons on) i also dont have any rear bar work on the back of my buggy to cover any of the pipes

hey phantom. if your buggy has previous rego papers/engineers to say it was legal once (not legal with a shot pan etc now from scratch) then it should only have to pass noise regs for the year the chassis was made. is this not correct? a 4 into 1 thunderbird exhaust should be under these limits. give custom offroad a call see what they say about the engineers problem.

Yeah I've looked at a lot of this, cos I really just want to get it on the road as a basic car, not for huge performance, etc.

The car has not been rego'd previously as a buggy and therefore I have to go through all of the engineering aspects from scratch.

However the exhaust issue was picked up by the rego inspectors, not the engineer. Also I reckon a 4 to 1 system would protrude almost as far as the standard syste, - protrusion was also an issue.

In short, I'm doing what I can to get this on the road as simply as possible. Down the road I might decide to put on a better system, etc, however at the moment I'm pulling in the belt as the project cost has already blown out.

I am a fan of the 4 into 1 thunderbird exhaust to.

That was until i experienced the exhaust a mate made up for his own buggy.

This is just as nice on the ears and doesn't effect its performance in anyway.

Check it out.

do you know what mufflers they are jace? has he used a different exhaust kit and modifyed from there or made from scratch?

The Mufflers are lukey product.
The rest he has made up himself

manx_xtc does the exhaust go 4 into one or are they seperate in the pics?

They are equal length tubes like the cannons are.

in other words they are seperate.

I have bascially the same set up as above, except i have two hotdogs instead of the mufflers, so is it true that i am not getting all the possible performance out of my engine even though the pipes are equal length? If so does anyone know how much power i could be loosing?

On my buggy I've always preferred the cannons for a couple of reasons, 1) Definitely the looks and 2) there's less to rust or at least less areas where salt laden sand can accumulate. On a 4 into 1 there's always that spot where the pipes come together that's a right bugger to keep clean and whenever I've had them that's where they've fallen apart. On the cannons though I've always had a bracket welded between the hotdog muffler and the pipework from 2 and 4 cylinders to stop any flexing when bouncing around. After 17 years with this buggy I've found the cannons to last about twice as long as 4 into 1s, this may not be a priority to you but it is to me. An alternative to get around this would be to get a 4 into 1 and have it hot aluminium sprayed which would make it last longer. As I say this is only my opinion based on experience.

have u noticed any change in performance in the two barry?

Not enough to worry about . As for noise bloody hell it's a VW they're always noisy! No as I said my priority was durability, the difference in engine performance was negligable, it may be more noticeable if the engine was a 1916 with all the bells and whistles but as a standard 1600 I wasn't too concerned. Now I've got a type4 it's all irrelevent to me.....unless someone makes dual cannons for one

the engine in the yellow one in the pics is a 2.2 ltr type 1 engine.
the exhausts do not effect its performance in any way at all.

Manxed69 on here runs a 1600 and dual cannons on his manx and doesn't have a problem with them.
